Abstract
An anti-wear compression ignition fuel composition for use in diesel engines comprising (1) from about 70 percent by weight to about 98.45 percent by weight of a monohydroxy alkanol having from 1-5 carbon atoms, (2) from about 1 percent by weight to about 25 percent by weight of a fuel oil boiling above the gasoline boiling range, and (3) a wear inhibiting amount of a dimerized unsaturated fatty acid. Optionally, said fuel composition may also contain an ignition accelerator such as an organic nitrate.

As a new composition of matter, an anti-wear compression ignition fuel composition for use in diesel engines comprising (1) from about 70 percent by weight to about 98.45 percent by weight of a monohydroxy alkanol having from 1 to 5 carbon atoms, (2) from about 1 percent by weight to about 25 percent by weight of a fuel oil boiling above the gasoline boiling range, and (3) a wear inhibiting amount of a dimerized unsaturated fatty acid.
A method for inhibiting engine wear in an internal combustion reciprocating diesel engine operating on a compression ignition fuel comprising (1) from about 70 percent by weight to about 98.45 percent by weight of a monohydroxy alkanol having from 1 to 5 carbon atoms (2) from about 1 percent by weight to about 25 percent by weight of a fuel oil boiling above the gasoline boiling range, and (3) a wear inhibiting amount of a dimerized unsaturated fatty acid, said method comprising (a) supplying to the fuel induction system of said engine said compression ignition fuel, (b) inducting air into the combustion chambers of said engine (c) compressing said air, (d) injecting said compression ignition fuel into said combustion chambers containing said compressed air, (e) igniting said compressed mixture, and (f) exhausting the resultant combustion products resulting in reduced engine wear in said engine.
A method for preparing a compression ignition fuel adapted for use in diesel engines having anti-wear properties which comprises blending (1) a wear inhibiting amount of a dimerized unsaturated fatty acid, with (2) from about 70 percent by weight to about 98.45 percent by weight of a monohydroxy alkanol having from 1 to 5 carbon atoms, and (3) from about 1 percent by weight to about 25 percent by weight of a fuel oil boiling above the gasoline boiling range.
